TRIMMER FOR VAULT-LIGHTS.

SPECIFICATION forming part of Letters Patent No. 520,273, dated May 22,1894.

Application filed December 16, 1893. Serial No. 493.805- (No model.)

To all whom, it may concern:

Be it known that I, PHILIP SOHWICKART, of Brooklyn, in the county ofKings and State of New York, have invented a new and Improved Trimmerfor Vanlt-Lights, of which the following is a full, clear, and exactdeseription.

The object of the invention is to provide a new and improved trimmer forvault lights, to conveniently and quickly cut or trim the surplusmaterial of the putty, cement or other substance employed for fasteningthe glass bulls-eyes in place in the metallic frame.

The invention consists principally of a central post adapted to besupported on the bullseye, and a cutter frame mounted to turn on thesaid post, and provided with cutters adapted to circularly trim thesurplus material of the fastening substance, at the joint of thebulls-eye and the frame.

The invention also consists of certain parts and details, andcombinations-of the same, as will be hereinafter described, and thenpointed out in the claims.

Reference is to be had to the accompanying drawings, forming a partofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a sectional side elevation of the improvement as applied;and Fig. 2 is a plan view of the finished vault light.

The improved trimmer is provided with a post A, having at its lower enda foot 13, formed on its under side with a recess or cavity adapted toengage a similarly-shaped projection 0, formed centrally on the top ofthe bulls-eye O, fastened in the metallic frame D, by means of putty,cement or other similar substance.

The upper end of the post A engages a socket F forming a part of a frameF, provided with downwardly-extending arms F projecting from the saidsocket F, and carrying at their lower ends cutters or scrapers G,adapted to engage the surplus material of the putty or other substanceE, so that when the frame F is turned on the post A and presseddownwardly, the said cutters will trim or cut the surplus material, soas to form a neat joint between the bulls-eye C and the metallic frameD. The two arms F are connected with each other by a cross bar A,provided with acentral aperture so as to form a bearing for the lowerpart of the post A.

From the upper end of the socket F projects a square or polygonal ofisetF adapted to be engaged by a wrench H, or other suitable tool forconveniently turning the said frame to cause the cutters G to remove thesurplus material at the joint of the bulls-eye with the frame. On theunder side of the socket F presses the upper end of a spring I, coiledon the post A and resting, with its lower end on a pin A secured in thesaid post, as plainly shown in Fig. 1.

The device is used as follows: After the bulls-eye O is pressed inposition on its seat I in the frame D, with the putty or other substancefilling the joint in the iron frame, then part of the surplus materialextends above the top surface of the bullseye and frame, and in order toconveniently and quickly remove this surplus material, I employ thetrimmer as shown in Fig. 1. The post A, with its foot B, is first seatedon the projection 0', the spring I then holding the frame F in anuppermost position so that the cutters G are above the surplus material.The operator now applies the tool H so as to turn the frame F, at thesame time pressing it downward to cause the cutters G to engage and trimthe surplus material, until the cutters finally pass onto the topsurface of the bulls-eye O and frame D atthe circular joint between thetwo.

It will be seen that this device can be readily set over each individualbulls-eye and its joint trimmed circularly in the manner abovedescribed.

. I do not limit myself to the particular form of footB on the post A,as a suction cup may be employed on the lower end of the post A toengage a smooth top of the bulls-eye 0.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. A trimmer for vault lights, comprising acentral post adapted to be supported on the bulls-eye, and, a cutterframe mounted to turn on the said post and provided with cutters adaptedto circularly trim the surplus material in the joint of the saidbulls-eye IOC and its metallic supporting frame, substantially as shownand described.

2. A trimmer for vault lights, comprising a central post provided with afoot adapted to engage the bulls-eye, acutter frame mounted yieldinglyon the said post and adapted to be turned thereon, and cutters held onthe said frame and adapted to circularly trim the surplus material atthe joint of the bulls-eye and its. supporting frame, substantially asshown and described.

7 3. The combination with a bulls-eye having a central projection, of apost provided with a recessed foot adapted to engage the saidprojection, a frame fitted to slide and mounted to turn on the saidpost, and cutters secured on the said frame and adapted to trim thesurplus material at the joint of the bulls-eye and its supporting frame,substantially as shown and described.

4. The combination with a bulls-eye having a central projection, of apost provided with a recessed foot adapted to engage the saidprojection, a frame fitted to slide and mounted to turn on the saidpost, cutters ser PHILIP SCHWICKART.
